Unable to resolve Ingress Contoller Load Balancer External IP using Azure DNS

Hi Team,
I've Installed NGINX Ingress Controller on AKS Cluster.

$ kubectl get svc -n ingress-nginx
NAME                                 TYPE           CLUSTER-IP     EXTERNAL-IP     PORT(S)                      AGE
ingress-nginx-controller             LoadBalancer   10.0.152.95    4.209.243.215   80:30970/TCP,443:31532/TCP   6h36m
ingress-nginx-controller-admission   ClusterIP      10.0.223.190   <none>          443/TCP                      6h36m

I've mapped the Ingress Controller LoadBalancer IP with Azure DNS Zone by creaitng A Record Set.

 kubectl describe svc ingress-nginx-controller -n ingress-nginx

As you can see I'm unable to reolve the domain (test.rdaksdemozone.com) to Ingress Controller Load Balancer External IP

Kindly help chekin this issue.
